sECTIoNAL woonEN PIPE-COVERING.

Application filed September 30, 1918. Seria1-No.

To all whom it concern:

Be it known that I, CHARLES In the accompanying drawings whichillustrate a preferred embodiment 'of the.

invention,

Figure 1 is a side elevation of the pipe covering showing severallengths, partly broken away, assembled end to end as they would be whenapplied to a pipe; m

Fig. 2 is a side elevation; partly in longitudinal section, of a lengthof the pipe covering;

Fig. 3 scale of thepipe covering;

' Fig. 4 is an end elevat on on an enlarged 7 scale viewed from the leftof Fig. 2, show f ing the tenon end;

Fig. 5 is an end elevation, viewed from the right of Fig. 2, showing thesocket end;

Fig. 6 is an end view of the tenon end illustrating a temporary binderfor holding the sections together for transportation or storage; and

Fig. 7 is a side elevation, partly broken away, showing temporary bining means at both ends.

The complete, assembled, tubular, wooden pipe covering is madetup of aseries of lengths A of a diameter appropriate to the pipe to which it isto be applied, and of convenient length, placed end to, end as shown inFig. 1. Each length of pipe covering is divided lengthwise into twoindependent separable sections, so that the two parts may be placedaround the pipe with their abutting edges forming closed joints 1,preferably rabbeted or provided with tongues and grooves. to form amatched joint, as shown. Each such section is made up of a number oflengthwise extending wooden staves 2, the staves of each section S.Win50, citizen of the United States of' America, and resident ofBrookline, in the county of exterior shoulder a is a cross section on anenlarged being .fastened together independently of the staves of theother section.

The preferred means for so fastening together thefstaves consists of awire 3 which is driven into and embedded in the ends of thestaves. IThe, ends-ofthe wire are bent or hooked; as shown at4, to provide afirmanchorage for the wire to bind the several staves to ether.

In or'er that tightly closed end joints may be provided betweensuccessive lengths of the covering one end is made with an other endwith an interior shoulder 7 and socket 8 adapted to receive and fit thetenon of the next adjoining length of covering.

The wire fastening 3 is embedded in these shoulders, and the hooks 4face outwardly or inwardly according as they are embedded in theshoulders 5 or 7. Instead of wire,

other fastening means such as metal strips could be sunk into the endsof wooden staves to bind them together, and such equivalent means arecontemplated in the claims.

The exterior of each shell or section may be coated with any suitablewaterproofing 'material 9, such as asphalt, or a similar waterproofingcomposition; and the interior may be covered with aheat insulatingfacing Specification of Letters Patent. i t t J 1 ,1920

and tenon 6, and the 1 10, such as wire mesh filled with asbestoscement. To make the continuous assembled structure completely waterproofa waterproofing cement may be applied to the tenon or socket, or both,before the lengths are fitted together end to end.

- The structure is applied to the piping by merely placing the twosections around the piping with their edges 1 abutting, and bind ingthem in place by suitable wires or bands extending around the outside ofthe covering. I I 1 To hold a pair of sections together temporarily fortransportation or storage, a removable band or hoop 11 (Figs. 6 and 7may be placed around the tenon 6, and a pair of straps 12 may befastened to the opposite end across the joints between the two sectionsby means of easily removable nails or staples.
